Posterior segment parameters after uveitic cataract surgery: A prospective study with 1-year results.

PURPOSE: To evaluate the changes in posterior segment after uncomplicated cataract surgery in uveitic patients. METHODS: Retinal nerve fiber layer thickness (RNFLT), ganglion cell layer thickness (GCLT), central macular thickness (CMT), and choroidal thickness (CT) of 38 eyes of 28 patients were measured pre- and postoperatively on day 1, week 1, and month 1, 3, 6, 9, and 12. RESULTS: The RNFLT increased after surgery. Although the measurements taken were higher than the baseline CMT at all postoperative times, no significant difference was detected between the paired comparisons. The GCLT was found to be higher than the baseline value in all quadrants at the 12th month. A decrease in CT was observed at 5 measured points on the 1st day compared to the baseline. CONCLUSION: During the 1-year follow-up, the effect of cataract surgery on the retina and choroid in uveitic eyes was most evident at the postoperative month 1.

Anterior segment parameters after uveitic cataract surgery: A prospective study with 1-year results.

PURPOSE: To determine the changes in anterior segment parameters in uveitic patients undergoing uncomplicated cataract surgery. METHODS: The best corrected visual acuity (BCVA), intraocular pressure (IOP), central corneal thickness (CCT), anterior chamber angle (ACA), anterior chamber depth (ACD), and axial length (AXL) of the 38 eyes of 28 well-controlled uveitic patients who underwent cataract surgery were monitored for 12 months. RESULTS: Mean BCVA improved significantly at the postoperative visits when compared to the baseline (all P<0.001). Mean CCT increased on the first day compared to the preoperative value (627.62±71.16 vs. 572.18±53.52 µm, P=0.015) and then returned to the preoperative value at 3 months (572.27±49.93 µm). ACA showed a significant increase postoperatively in the first month (54.65±5.52 vs. 43.50±9.13°) and then decreased at 3 months (51.85±5.52°), remaining stable afterwards (51.73±6.59° at 12 months). ACD as measured by Sirius topography and IOLMaster 500 was higher at the follow-up times compared to the preoperative value (P<0.001). AXL at 1. month was significantly lower than the preoperative level (23.14±0.74 vs. 23.54±0.68 mm, P=0.003). CONCLUSION: Following successful cataract surgery in well-controlled uveitic eyes, the CCT showed a rapid increase on the first day and then decreased to the preoperative level at the third month. ACA increased in the postoperative first month and then decreased, but it was higher than the baseline at all postoperative visits. ACD increased in the postoperative first week.

The role of meibomian gland dysfunction on the development of dry eye disease in patients with facial nerve palsy.

PURPOSE: To investigate whether meibomian gland dysfunction is the cause of dry eye in facial nerve palsy and to identify the possible relationship between the grades and durations of facial nerve palsy and meibomian gland dysfunction. METHODS: This prospective observational study included 63 patients with unilateral facial nerve palsy. Facial nerve function and severity were assessed using the House-Brackmann grading system. Unaffected contralateral eyes were used as the control group. The following parameters were compared: tear breakup time, Schirmer 1 test score, area and density scores for corneal fluorescein staining, eyelid abnormality, meibomian gland expression, meibography scores, and areas of meibomian gland loss. A Pearson correlation analysis was performed between the grades and durations of facial nerve palsy and meibomian gland dysfunction. RESULTS: The eyes affected by facial nerve palsy demonstrated significantly lower tear breakup time (p<0.001) and significantly higher values for corneal fluorescein staining (p<0.001), Schirmer 1 test score (p=0.042), lid abnormality score (p<0.05), meibomian gland expression level (p=0.005), meibography scores (p<0.05), and areas of meibomian gland loss (p<0.05). The grade and duration of facial nerve palsy significantly correlated with meibomian gland dysfunction (p<0.05). CONCLUSIONS: Meibomian gland dysfunction has a significant contribution to the development of dry eye disease after facial nerve palsy. Furthermore, a strong correlation was observed between the grades and durations of facial nerve palsy and meibomian gland dysfunction.

A Rare Patient With Orbital Apex Syndrome, Anterior Uveitis, and Necrotizing Scleritis Due to Herpes Zoster Ophthalmicus.

The purpose of this study was to describe a patient of orbital apex syndrome, anterior uveitis, secondary glaucoma, corneal dellen, and necrotizing scleritis following an attack of herpes zoster ophthalmicus, and the placement of a pericardial patch graft. A 64-year-old male patient with blepharoptosis of his right eye and multiple vesicles on the forehead, nose and cheeks, limitation on all gazes, blepharoptosis, and exophthalmia was eventually diagnosed with ophthalmic zona with orbital apex syndrome. After the treatment with systemic antiviral and steroid, there was complete recovery of the unilateral vesicular eruption, ophthalmoplegia, and ptosis at the third month follow-up. However, anterior uveitis, necrotizing scleritis, secondary glaucoma, and corneal dellen developed during follow-up. At the ninth month, pericardial patch graft (Tutoplast) was placed due to progression of the scleral thinning. Graft vascularization was completed. Careful and long-term follow-up of patients with ophthalmic zona is required for possible ophthalmic complications of varicella zoster virus infections. A pericardial patch graft might be placed due to the development of necrotizing scleritis.

Transection of Nasolacrimal Duct in Endoscopic Medial Maxillectomy: Implication on Epiphora.

OBJECTIVE: Management of the nasolacrimal system is usually recommended during medial maxillectomy via external approach because of reported higher rates of postoperative epiphora. Association of the endoscopic medial maxillectomy (EMM) with epiphora, however, is not clearly stated. In this study, we attempted to evaluate whether patients develop epiphora after simple transection of the nasolacrimal duct during EMM. PATIENTS AND METHODS: Medical records of 26 patients who underwent endoscopic tumor resection for inverted papilloma (IP) were retrospectively reviewed. Patients who underwent EMM with nasolacrimal canal transection were included and recalled for lacrimal system evaluation. Twelve patients were eligible for inclusion and fluorescein dye disappearance test (FDDT) was performed for each patient. Patient demographics, tumor data, surgical procedures, and follow-up time were recorded. RESULTS: Of the 12 patients included in the study, 6 underwent canine fossa transantral approach concurrently with EMM. The mean duration of follow-up was 21.1 months (range, 6-84 months). Eight patients were graded as 0, whereas 4 patients were graded as 1 according to FDDT. All test results were interpreted as negative for epiphora. All patients were completely symptom free of epiphora. CONCLUSIONS: Epiphora after EMM with nasolacrimal canal transection among patients with sinonasal tumors appears to be uncommon. Therefore, prophylactic concurrent management of nasolacrimal system including stenting, dacryocystorhinostomy (DCR), or postoperative lacrimal lavage are not mandatory for all patients.

Osteoplastic flap approach versus orbitotomy in case of orbitofrontal cholesterol granuloma.

A 44-year-old man developed a slow-growing painless left superolateral orbital mass that extended into the frontal sinus with a complaint of ptosis. Magnetic resonance imaging revealed a heterogenous hyperintense lesion confined to the left frontal bone and superior orbit. The osteoplastic frontal sinus approach was performed to drain supraorbital cholesterol granuloma cyst and for curetting the capsule. Orbitofrontal cholesterol granuloma characteristically arises in the diploe of the superolateral frontal bone. The traditional approach for a primarily orbitofrontal cholesterol granuloma is the transorbital approach including anterior orbitotomy or lateral orbitotomy. However, the osteoplastic approach should be kept in mind as an alternative aprroach for the management of supraorbital lesions in patients with well-pneumatized frontal sinus.

Orbital Apex Syndrome Secondary to Herpes Zoster Ophthalmicus.

A 49-year-old woman who complained of lacrimation, foreign body sensation, and eyelid oedema presented to our outpatient clinic. External examination identified erythematous rash with vesicles on the left eyelid, dorsum of the nose, and forehead of the patient. She was diagnosed to have herpes zoster ophthalmicus (HZO), and was started on oral brivudine and topical acyclovir. On the third day of the treatment, visual acuity of left eye was reduced; left blepharoptosis and total ophthalmoplegia had developed. Orbital magnetic resonance imaging (MRI) showed enlargement of the extraocular muscles, and perineural enhancement of the optic nerve on that side. Oral brivudine was replaced with intravenous acyclovir, and oral corticosteroid was initiated. Complete resolution of proptosis and restriction of eye movements were achieved, and significant improvement of visual acuity was observed within a week. Orbital apex syndrome, a severe and rare complication of herpes zoster infection, can develop despite antiviral treatment. Rapid institution of appropriate therapy may provide complete recovery.
