Abstract A multi-functional self-examination ophthalmic device for remote eye examinations has been studied in this paper. The device integrates two standard ophthalmic examinations: slit-lamp and visual acuity. Testing of the device has been performed in a preliminary clinical study. The results show good and comparable images to those of conventional instruments routinely used in ophthalmic clinics. The device can be used in a myriad of remote settings including home monitoring.

Cyclodialysis Cleft

Purpose.To propose a novel surgical method for the localization and management of traumatic cyclodialysis clefts.Methods.Five patients with traumatic cyclodialysis clefts who underwent the innovative surgery were retrospectively reviewed. The new method was introduced to repair a cyclodialysis cleft with two running sutures from the middle to each end of the cleft under the guidance of a probe. Preoperative and postoperative visual acuity (VA), intraocular pressure (IOP), slit lamp and gonioscopic results, ultrasound biomicroscopy (UBM), and optical coherence tomography (OCT) findings were recorded.Results.Cyclodialysis clefts were completely closed postoperatively in four patients (four eyes); this was confirmed by progressively improved VA, restoration into the normal range of the IOP, disappearance of suprachoroidal fluid, and reduced macular edema. Only one patient with multiple clefts had an incomplete reattachment.Conclusions.This clinical study offers a novel and efficient method to localize and repair the cyclodialysis clefts.

Early Occurrence

Background: Posterior capsular clarity is important for long-term visual gain. Postoperative visual acuity could be reduced due to posterior capsular or intraocular lens opacification, which occur months or years after cataract surgery. We report early occurrence of posterior capsular calcification without opacification of intraocular lens. Case: We report the case of a 78-year-old male who had undergone phacoemulsification with implantation of hydrophilic intraocular lens (IOL) in the left eye for cataract. The patient was non-diabetic, and the surgical procedure was uneventful. On the third postoperative day, fine granular deposits were found on the mid-peripheral part of the posterior capsule. No deposits were found on IOL. The patient presented with diminished vision four months after surgery. Slit-lamp examination revealed distinct areas of calcification with an early opacification of the posterior capsule and no IOL calcification. Neodymium doped: YAG capsulotomy was done to clear posterior capsular opacification, and the patient regained visual acuity of 20/20. To the best of our knowledge, this report is the first to investigate posterior capsular calcification without opacification of IOL in a patient without any known etiological factors. Conclusion: This case is reported to stimulate future study on the use of BSS plus and the development of posterior capsular or IOL calcification. Nepal J Ophthalmol 2016; 8(15): 91-94

Purpose To evaluate the therapeutic effect of incorporating continuous administration of voriconazole in the treatment of recalcitrant fungal keratitis. Methods In this prospective case study, 5 consecutive patients (5 eyes) with fungal keratitis were treated with a standard protocol after the failing maximal conventional medical treatment. The protocol involved continuous lavage of the ulcer with 1% voriconazole through an irrigator for 2 h, twice a day, combined with local and systemic antifungals. Visual acuity, slit lamp findings of the ulcer, and fungal hyphae density by confocal microscope were documented, respectively. Results In 4 patients, the clinical symptoms and slit lamp examination were significantly improved after only 3 days of treatment. The hyphae were shown to decrease in number and morphologically fragmented in corneal stroma by confocal microscopy. After the infection was controlled, 2 cases required further keratoplasty. In one case, the treatment was deemed ineffective and a conjunctival flap had to be created to help control the infection. In all 5 patients, the best spectacle-corrected visual acuity had improved after treatment. With more than 3 months of follow-up, no recurrence of infection was seen in any cases. Conclusion Our treatment protocol demonstrated improvement in the treatment of clinically resistant fungal keratitis. Continuous lavage of voriconazole is easy to be implemented and well-tolerated by patients. Modification of the current protocol should be further explored to optimize the therapeutic effectiveness in future.

Herpes zoster ophthalmic is a common condition in the elderly or in the immunocompromised people. We present the case of a 32-yearold female patient, without any particular history, who consulted the emergency room for a red right eye with major chemosis, palpebral edema, and decreased visual acuity. There was also a crusty rash in the V1 territory, suggesting herpes zoster. Visual acuity was 2/10 in the right eye and 10/10 left eye (Figure 1 and 2). Examination at the slit lamp revealed a non-hypertensive granulomatous anterior kerato-uveitis of the right eye. Given the severity of the lesion, an immunodepressive background was suspected, HIV serology came back positive.
