Comparison of two ultra-widefield imaging for detecting peripheral retinal breaks requiring treatment.

AIM: To compare the sensitivity of Optomap Panoramic 200 and Clarus 500 in detecting peripheral retinal breaks that required treatment. METHODS: This prospective study enrolled consecutive patients undergoing laser for treatment-requiring peripheral retinal breaks from May 2019 to July 2019. The patients first underwent indirect ophthalmoscopy examination with scleral indentation by a retinal consultant and then ultra-widefield imaging by a single trained technician on Optomap 200 and Clarus 500 in all nine ocular gazes. The images were analysed by two independent investigators to look for the number and location of the breaks. The sensitivity of each platform was calculated as the number of treatment-requiring breaks identified by the system divided by the number of breaks identified on clinical examination. RESULTS: Clinical examination of 49 eyes (41 patients) showed 116 treatment-requiring breaks. Overall sensitivity for identifying such breaks for Optomap and Clarus was 80.2% (n = 93) and 74.1% (n = 86) respectively (p = 0.274). The sensitivities in superior (p = 0.665), temporal (p = 0.146) and inferior (p = 0.889) quadrants were statistically similar for both the platforms. The sensitivity of Optomap was slightly higher than Clarus in emmetropic (p = 0.046) and phakic (p = 0.061) eyes, but similar in myopic (p = 0.448) and pseudophakic (p = 0.191) eyes. CONCLUSION: The ability to detect treatment-requiring retinal breaks is similar for both Optomap and Clarus systems.

Combined treatment modality including topical 20% fluorescein dye in the management of phthiriasis palpebrarum - A case series.

Purpose: To study the clinical presentations and outcomes of phthiriasis palpebrarum (PP) managed with combined treatment modality comprising of 20% fluorescein dye, mechanical removal of the ectoparasites, and topical application of antibiotic eye ointment with paraffin base. Methods: This is a prospective interventional noncomparative hospital-based series of 13 patients of PP. All the patients underwent local application of 20% fluorescein dye over the eyelashes and eyebrows of both the eyes followed by the mechanical removal of all the ectoparasites and trimming of the eyelashes from the base followed by application of ophthalmic ointment. Results: Mean age of the patients was 28 ± 22 years (range 3-60 Years). Out of the total of 13 patients, 11 patients (85%) were having bilateral involvement. The mean duration of symptoms in 11 patients (rest 2 were accidental findings) was 4 ± 3 weeks (range 1-10 weeks). Three patients (23%) had a history of sexual contact with possible parasite-infested partners. Four patients (31%) had additional parasites in the pubic area or torso. All the patients were completely parasite free at the end of 1 month. There was no infestation of the treating medical personnel from the patient. The average follow-up was 8 ± 5 months (range 3-21 months). Conclusion: Itching and irritation of the eyes were the most common presentations of PP. Combined treatment modality comprising of 20% fluorescein dye, mechanical removal of ectoparasites, and topical application of antibiotic eye ointment with paraffin base is effective in the management of PP.
