Concurrent laser-assisted in situ keratomileusis with high-fluence cross-linking versus laser-assisted in situ keratomileusis only in treatment of hyperopia p. 117
Ahmed M Eid, Ahmed A Abdelghany, Ahmed S Abdelhalim, Ahmed M Sabry
DOI:10.4103/ejos.ejos_38_19  
Purpose To compare refractive and corneal structural stability after laser-assisted in situ keratomileusis (LASIK) with and without concurrent prophylactic high-fluence cross-linking in the treatment of hyperopia. Patients and methods In an interventional prospective nonrandomized comparative study, 50 eyes of 25 patients with hyperopia (+1 D to +6 D) or hyperopic astigmatism (up to 4 D) underwent customized LASIK with concurrent prophylactic high-fluence cross-linking in the right eye (group A) and customized LASIK only in the left eye (group B). Main outcome measures included postoperative uncorrected visual acuity (UCVA), manifest and cycloplegic refractive spherical equivalent, keratometric readings, and spherical aberrations throughout the 2 years of postoperative follow-up. Results There were statistically significant changes in all studied parameters between preoperative and postoperative follow-up at 3 months, 1 year, and 2 years in both groups, and these changes remained stable in group A throughout the follow-up period. UCVA was statistically significantly better in group A compared with group B at 3 months (P=0.02). In group B, UCVA was highly statistically significant better at 1 year compared with that at 3 months (P=0.005). Conclusion LASIK with concurrent prophylactic high-fluence has better visual outcomes and stability compared with LASIK alone in the treatment of hyperopia.

Ganglion cell analysis versus retinal nerve fiber layer thickness in glaucoma diagnosis p. 122
Tarek Tawfik Soliman, Elham Abd Alazeem Gad, Sarah Mohamed Selim
DOI:10.4103/ejos.ejos_45_19  
Background Glaucoma is a progressive optic neuropathy, which can result in irreversible blindness. The main pathologic change in glaucoma is retinal ganglion cell loss. The macula has the greatest density of retinal ganglion cells (∼50%). The advent of spectral domain-optical coherence tomography (OCT) technology has allowed advanced macular imaging protocols to play an important role in the diagnosis and monitoring of glaucoma. The ganglion cell analysis is obtained by the Cirrus HD-OCT system segments and measures the thickness of the ganglion cell‑inner plexiform layer, thereby potentially increasing its diagnostic accuracy compared with conventional peripapillary retinal nerve fiber layer (RNFL) thickness measurement. Patients and methods The study was done on 40 eyes of 40 patients, and patients were divided into two groups: Group 1 included 20 adult patients more than 18 years who were diagnosed with primary open-angle glaucoma. Group 2 included 20 normal controls. One eye of each individual was prospectively enrolled. The OCT was done using 3D-OCT 2000 (Topcon) to evaluate the following: RNFL parameters (average total thickness, superior average thickness, and inferior average thickness) and ganglion cell complex (GCC) parameters (total average thickness, superior average thickness, and inferior average thickness). Result There was a positive statistically significant correlation of high probability between the two groups regarding RNFL thickness (P<0.001). There was a positive statistically significant correlation of high probability between the two groups regarding GCC thickness (P<0.001). There was a positive statistical significant correlation of high probability between the groups regarding intraocular pressure (P<0.001). There was a positive statistical significant correlation of high probability between the groups regarding cup-to-disc ratio (P<0.001). Conclusion Early diagnosis of glaucoma and early initiation of treatment is extremely important, as further vision loss can be stopped or slowed down. RNFL and GCC measurement with spectral domain-OCT could provide important information for detection and evaluation of glaucoma. There is strong positive correlation between the RNFL thickness and the GCC thickness in the glaucomatous patients.

Ahmed E.M Ramadan, Ghada Z. El-Abedin Abd El-Rahman Rajab, Abd El-Khalik I El-Saadani, Hatem M Marey
DOI:10.4103/ejos.ejos_55_19  
Background Duane retraction syndrome (DRS) is a congenital ocular motility disorder most commonly characterized by the inability of the eye to abduct, sometimes limitation of adduction, and globe retraction with palpebral fissure narrowing on adduction. Aim To study the clinical features, management, and outcome of DRS. Patients and methods A prospective, nonrandomized study was carried out on patients attending the Outpatient Clinic of Ophthalmology in Menoufia University Hospital during the period of study from June 2017 to July 2019. This study was conducted on 51 patients with DRS. Ocular and systemic features were studied. Surgery was done when indicated to eliminate upshoot or downshoot, face turn with a horizontal deviation, and globe retraction. Preoperative and postoperative ocular deviation, angle of head turn, and severity of limitation in abduction and adduction were detected and analyzed. Results Type I DRS was more common (70.6%), with female preponderance (52.9%) and a predilection for the left eye (70.6%). Twenty-one (41.2%) cases were operated, by recessing MR and/or lateral rectus (LR) muscles and/or Y-splitting and acceptable improvement was detected. Mean esotropic DRS improved from 18±4.02 to 3±2.8 (P<0.001) and mean exotropic DRS improved from 14±2 to 5±1.4 (P<0.01). Upshooting/downshooting and narrowing of the palpebral fissure showed significant improvement (P<0.001 and <0.03, respectively). Conclusion Proper diagnosis of patients with DRS and proper plan for surgical management can reduce several complications with satisfactory postoperative outcomes.

Unilateral congenital glaucoma may be the earliest presenting sign of orbitofacial neurofibromatosis and intracranial lesions: a case series p. 137
Mohamed A Zayed, Rania A El Essawy, Sahar A Tabak, Amanne F Esmael
DOI:10.4103/ejos.ejos_52_19  
Purpose The aim was to report a number of cases initially presenting with unilateral congenital glaucoma within the first year of life that subsequently were found to be associated with the orbitofacial variant of neurofibromatosis-1 (NF1) as well as with variable intracranial lesions. Patients and methods The records of 340 patients presenting with unilateral congenital glaucoma were retrospectively reviewed to identify patients who subsequently developed orbitofacial NF ipsilateral to the glaucoma or other manifestations of NF1. All clinical, radiological, or histopathological data for enucleated globes, if available, were reviewed. Results Seven patients were identified with a mean age at presentation of 4.3±5.4 months. They presented with unilateral buphthalmos and high intraocular pressure with subtle proptosis and/or lid swelling. The mean age at NF1 diagnosis was 23.14±18.5 months. Initial imaging reports were either read as ‘normal’ or described a lesion near the cavernous sinus (CS): CS thrombosis, clival meningioma, histiocytosis, carotid cavernous fistula, or CS hemangioma. Once the diagnosis of NF1 was made, subsequent imaging studies (computed tomography and/or MRI) showed a defect at the greater wing of sphenoid bone (all patients); neurofibroma involving the CS, orbit, and nearby intracranial and subcutaneous structures to varying degrees (all patients); and hamartomas at the level of the basal ganglia (six patients). Associated intracranial lesions were sphenoid wing meningioma, optic nerve glioma, and trigeminal schwannoma. Histopathology of two enucleated eyes showed glaucomatous changes with prominent ciliochoroidal hyperplasia in one case and a ciliary body schwannoma in another. Conclusion In newborns with unilateral congenital glaucoma, the differential diagnosis should include NF1. Targeted radiologic examinations may reveal diagnostic signs and decrease disease morbidity. The glaucoma surgeon may opt for earlier aggressive intervention in this potentially blinding disease.

Marwa S.A Ahmed, Olfat A Hassanin, Ahmed I Abou El-Enin, Afaf H Rashwan
DOI:10.4103/ejos.ejos_65_19  
Background Biomechanics of the cornea is represented by corneal hysteresis (CH), which is defined as the viscous damping owing to viscoelastic resistance of the cornea to deformation. Aim Assessing intraocular pressure (IOP) and corneal biomechanics alterations after phacoemulsification. Patients and methods Thirty eyes were uneventfully operated on using phacoemulsification. CH, corneal resistant factor (CRF), corneal compensated intraocular pressure (IOPcc), and Goldmann correlated intraocular pressure (IOPg) values were recorded by ocular response analyzer (ORA). Central corneal thickness (CCT) was evaluated using pentacam preoperatively and postoperatively after 1 day, 1 week, and 1 month. Results Patients comprised 22 males and 8 females, with a mean age of 63.8±6.8years. Preoperative mean CCT was 532.4±39.2 µm, mean CH was 9.4±1.7 mmHg, mean CRF was 9.5±2.0 mmHg, mean IOPg was 15.4±3.9 mmHg, and mean IOPcc was 17.1±3.6 mmHg. CCT significantly increased after 1 day and significantly decreased after 1 week, and decreased again after 1 month but remained significantly higher. CH decreased significantly after 1 day and increased to the preoperative values after 1 week and 1 month. CRF significantly increased after 1 day and then decreased significantly after 1 week and remained significantly lower. Both IOPcc and IOPg insignificantly elevated after 1 day, then significantly declined after 1 week, and insignificantly increased after 1 month but was still lower than the preoperative value. CH, CRF, and CCT correlated significantly except for 1 day after surgery. Conclusion Cataract surgery causes corneal structural alterations, changing biomechanical properties and IOP initially. CCT contributes in these parameters, as there is a correlation with CH and CRF.

Comparative study of two different techniques of diode laser transscleral cyclophotocoagulation in management of refractory glaucoma p. 154
Ahmed F Gabr, Muhammad M.A El Razeq, Abdalla M.A Abdalla
DOI:10.4103/ejos.ejos_66_19  
Purpose The aim was to compare between two techniques of diode laser transscleral cyclophotocoagulation in treatment of refractory glaucoma, that is, standard titratable (audible pops’ technique) versus slow coagulation technique, regarding and efficacy. Patients and methods In this prospective randomized study, 40 patients with refractory glaucoma were divided into two study groups: group A underwent standard technique of diode laser transscleral cyclophotocoagulation (audible pops technique), and group B underwent slow coagulation technique of diode laser transscleral cyclophotocoagulation. Patients were followed up at 1 week, 1 month, 3 month, and 6 month duration postoperatively, and changes in visual acuity, intraocular pressure (IOP), as well as postoperative complications were documented. Results The mean IOP was reduced significantly from 46.3±8.9 to 18.9±5.45 mmHg in patient of group A and from 42.8±8.53 to 20.05±8.28 mmHg in patient of group B at the end of 6-month follow-up (P<0.0001). The mean number of postoperative antiglaucoma drugs needed to control IOP was also reduced significantly in both groups. No serious complications such as hypotony were reported in the two study groups. Conclusion Both techniques of diode transscleral cyclophotocoagulation were of near equal safety and efficacy in treatment of refractory glaucoma with different underlying etiologies. Both had good efficacy in IOP lowering, reduced number of antiglaucoma medications used by patients, and relieved pain, with near equal incidence of postoperative complications.
