Purpose: To investigate the safety of accelerated corneal collagen cross-linking (A-CXL) in patients with keratoconus on the basis of thickness analysis measurements of retinal layers and retinal morphology.
Study Design: This was a retrospective and comparative study.
Methods: The study included 64 eyes of 32 patients with keratoconus disease.
Purpose Of The Study: To investigate the change in individual retinal layer thickness by spectral-domain optical coherence tomography (SD-OCT) in eyes underwent femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) and photorefractive keratectomy (PRK).
Methods: In patients who underwent PRK and FS-LASIK, changes in the thickness of all retinal layers in the foveal, parafoveal, and perifoveal regions were evaluated by SD-OCT automated segmentation analysis at pre-operatively and different time points post-operatively.
Results: Seventy-one eyes of 71 patients (38 patients in PRK, 33 patients in LASIK) were included.
The purpose of the study is to describe cilioretinal artery (CILRA) occlusion that is presumed to be associated with COVID-19 without severe respiratory distress and inform ophthalmologists of unusual ocular presentations of COVID-19. Here, we present the first case of a patient with isolated CILRA occlusion and paracentral acute middle maculopathy (PAMM) after recently polymerase chain reaction-proven COVID-19. A 26-year-old female patient presented with a visual field defect in her left eye for 2 days and decreased vision compared to her right eye.

We also aim to review MSS patients' ocular manifestations to provide a basis for future clinical trials and improve MSS patients' ophthalmologic care.
Case Description: Both patients presented with global developmental delay, microcephaly, cerebellar ataxia, and myopathy.
Purpose: To present the different clinical manifestations of rhino-orbital mucormycosis (ROM) co-infection in severe COVID-19 patients.
Study Design: Prospective observational clinical study METHODS: Among 32,814 patients hospitalized with the diagnosis of COVID-19 between March 2020 and December 2020 in our center, eleven microbiologically confirmed ROM co-infection cases in severe COVID-19 patients were evaluated.
Results: There were nine men and two women with a mean age of 73.
Purpose: Walker-Warburg syndrome (WWS) is a rare autosomal recessive disorder characterized by congenital muscular dystrophy and severe brain and eye malformations. This study aims to analyze genotype-phenotype correlations in WWS with a novel cytidine diphosphate-l-ribitol pyrophosphorylase A () mutation in different clinical manifestations.
Case Description: We report a girl with a presentation of multiple brain and ocular anomalies.
Purpose: To determine and compare the thickness of the ganglion cell-inner plexiform layer (GCIPL), the thickness of the retina nerve fiber layer (RNFL), and the parameters of the optic nerve head (ONH) in exfoliative glaucoma (XFG), primary open-angle glaucoma (POAG), and control eyes using optical coherence tomography (OCT).
Methods: The study was a retrospective observational cross-sectional study of 43 eyes of patients with XFG, 44 eyes of patients with POAG, and 37 eyes of healthy participants. Visual acuity, intraocular pressure, central corneal thickness, rim-area, disc-area, average cup/disc ratio, vertical cup/disc ratio, cup volume, average RNFL thickness, and GCIPL (average, minimum, superior, superotemporal, superonasal, inferior, inferotemporal, and inferonasal) thicknesses were determined.

Objectives: To examine the relationship between keratoconus (KC) stage and the thickness of the retinal layers.
Materials And Methods: Retinal layer thicknesses were compared between 85 eyes of 85 KC patients and 40 eyes of 40 controls similar in age, sex, and axial length. KC patients were staged as stage 1, 2, or 3 according to the Amsler-Krumeich staging system, and segmentation of the retinal layers was performed with spectral domain optical coherence tomography automatic segmentation program.
: To compare surgery's effect with nitinol flex loop (NFL) or forceps on retinal layers and functional outcomes in the primary epiretinal membrane (ERM).: The operations were classified according to the use of the NFL or forceps. Automatic segmentation of the individual inner retinal layers was performed by spectral-domain optical coherence tomography software, and best-corrected visual acuity (BCVA) before surgery and at the last follow-up visit postoperatively were compared.
