We conclude that the use of the Ologen implant in SST is comparable to the use of MMC with advantage of avoiding the potential dangerous complications related to MMC use in the early (12 months) follow-up period.

The results from combining topical with oral beta blockers showed that topical beta blockers are of additive value in treating superficial periocular infantile hemangioma in the early proliferative stage. [J Pediatr Ophthalmol Strabismus. 2018;55(1):37-42.].

Purpose:To compare the efficacy of intravitreal injection of bevacizumab alone or combined with intravitreal triamcinolone as the primary treatment for cases with diabetic macular edema (DME).Methods:Ninety eyes were enrolled in one of the three study arms; where intravitreal triamcinolone acetonide (IVT) was used in group I, IVT/intravitreal bevacizumab (IVT/IVB) in group II, and IVB in group III. The visual acuity (VA) and central macular thickness (CMT) were used as the outcome measures, where the results of each group were calculated and compared with the results of the other.Results:There was significant improvement in the VA in the three study groups at weeks 6 and 12; with regards to the intraocular pressure (IOP), there was significant difference at week 6 in the IVT and IVT/IVB groups, and at week 12 in IVT/IVB group, and nonsignificant difference at week 6 in the IVB group and at week 12 in IVT and IVB groups.Conclusion:From this study, we conclude that IVB is an effective drug for treatment of DME, and has a long lasting effect when compared with IVT and when compared with combined IVT/IVB; adding IVT does not affect the outcome measures except for elevating the IOP in treated patients in the early post-injection period.

Purpose: Evaluation of computer based color deficiency test. Materials and Methods: Two hundred and sixty seven volunteers have been checked using both traditional Ishihara plates and a computer diagnosis program using LCD monitors. Results: The prevalence of red green color vision deficiency (RG-CVD) was 8.75% of male participants, no female participants were diagnosed, both in the paper based test, and in the computer based test. Computer based test gave 100% sensitivity and 98.78% specificity. Conclusion: Presenting the computer based color deficiency test software on LCD screen can be used for screening of color vision deficiency with nearly similar sensitivity and specificity to the Ishihara test with the advantage reducing the cost through decreasing required resources over time, and decreasing the time to analyze the results.

PurposeTo evaluate the outcome of collagen cross-linking (CXL) without corneal epithelial debridement in patients treated for progressive keratoconus for whom the standard epithelium-off treatment cannot be applied, as their central corneal thickness (CCT) is less than 400 μm.Patients and methodsThis was a prospective, uncontrolled, interventional study involving 32 eyes of 30 patients with progressive keratoconus and CCT of less than 400 μm. All patients received CXL treatment with application of riboflavin and exposure to ultraviolet light A for 30 minutes without corneal epithelial debridement. Patients were followed up to 12 months postoperatively. The main outcomes were changes in maximum-K reading, manifest refractive spherical equivalent, CCT, and best-corrected visual acuity (logarithm of minimum angle of resolution). Patients were also asked to report any pain or discomfort during the procedure.ResultsAt the end of the 12-month follow-up, CCT showed no significant change: from 392±5.17 μm preoperatively to 390±4.45 μm (P=0.102). Maximum-K reading decreased significantly, from 49.19±2.30 D preoperatively to 46.96±6.03 D postoperatively (P<0.05). The mean manifest spherical equivalent showed no significant change: from 4.04±1.51 D preoperatively to 4.17±1.63 D postoperatively (P=0.110). Mean best-corrected visual acuity showed no significant change: from 0.29±0.12 preoperatively to 0.31±0.11 postoperatively (P=0.110).ConclusionEpithelium-on CXL exhibits potential as a method for treating patients with progressive keratoconus and CCT of less than 400 μm, in which the standard epithelium-off CXL cannot be applied. Over 12 months of follow-up, the epithelium-on CXL was safe and effective, with results comparable to that achieved with the epithelium-off technique in thicker corneas, and reduced rates of operative and postoperative discomfort.

Higher incidence of affections and complications has appeared in farmers, rural area residents, and illiterates which are considered the main predisposing factors for ulcer resistance. According to culture results, bacterial organisms (especially Staphylococcus aureus) were the main cause of resistant corneal ulcers.

The prevalence of VKC differs according to the age group of included cases and the local temperature of the study area. School attendance, performance, lifestyle, and social activities were negatively affected by VKC.

This study shows that using intraoperative MMC (0.2 mg/mL) in contracted socket reconstruction plays a significant role in maintaining prosthetic eye. To the best of our knowledge, this study is the first to use MMC on a relatively large scale of patients with contracted socket. However, the follow-up period was relatively short and further work is required to verify the effect of MMC on a longer follow-up period.
