ABSTRACT

PURPOSE: Several studies have demonstrated decompensation of intraocular pressure (IOP) control following phacoemulsification in eyes with a functioning trabeculectomy. Limited evidence base suggests that this effect is minimal in eyes with functioning glaucoma drainage devices (GDD). The aim of this study was to report on glaucoma control after phacoemulsification in eyes with a functioning GDD compared to eyes with a functioning trabeculectomy. METHODS: Single-centre retrospective comparative study of patients with a functioning non-valved GDD (Baerveldt 350; Johnson & Johnson Surgical Vision) or trabeculectomy undergoing phacoemulsification. Glaucoma outcomes including IOP, cup:disc ratio (CDR), global retinal nerve fibre layer (RNFL) thickness and visual field mean deviation (MD) are reported. Failure was defined as IOP rise > 20% from baseline. RESULTS: Fifteen eyes with a functioning trabeculectomy and twenty-three eyes with a functioning GDD with 24-month post-phacoemulsification data were identified. Mean IOPs were significantly lower in the trabeculectomy group at month 24 compared to the GDD group, 9.5 and 15.9 mmHg (p = 0.001) respectively. At month 12, there was significant worsening on MD in GDD group compared to trabeculectomy group, - 20.0 dB and - 11.3 dB respectively (p = 0.03). A greater proportion of eyes failed in the GDD group compared to the trabeculectomy group, N = 15 (65%) and n = 7 (47%), p = 0.26. CONCLUSION: As with functioning trabeculectomies, phacoemulsification should be approached with similar caution in eyes with functioning GDD. An existing GDD is at least as likely to fail following clear corneal phacoemulsification as an existing trabeculectomy and non-augmented GDDs may be at greater risk.

ABSTRACT

PURPOSE: The purpose of this study was to analyze the diagnostic and therapeutic approach of five cases with optic disc pit (ODP) maculopathy. MATERIALS AND METHODS: This was a retrospective study of five patients diagnosed with ODP maculopathy. Four of these cases had unilateral involvement, whereas one case had bilateral findings. The medical notes of these individuals were reviewed in order to record the presenting symptoms, clinical signs, visual acuity (VA), imaging, management, and the final visual outcome on their last follow-up appointment. RESULTS: The first patient (53-year-old female) underwent a left pars plana vitrectomy (PPV) combined with inner retinal fenestration, endolaser, and perfluoropropane (C3F8) gas tamponade and her VA improved from 6/24 to 6/9 Snellen. A focal retinal laser treatment was carried out on our second patient leading to decrease of the subretinal fluid but had a poor visual outcome due to the underlying secondary glaucoma from iris melanoma treatment in the past. The third patient was an asymptomatic 7-year-old girl in which the maculopathy resolved spontaneously without any surgical intervention with a final VA of 6/5. The fourth and fifth patients were asymptomatic with good vision in both eyes and were, therefore, only monitored with follow-ups. CONCLUSION: ODP maculopathy remains a challenging clinical entity for a vitreoretinal surgeon. The current management for ODP maculopathy involves surgical procedures with PPV being a common treatment of choice. Spontaneous resolution of ODP maculopathy has also been reported. Our study highlights the contrasting management that can be adopted in the treatment of ODP maculopathy, and there is not one definite treatment for this condition.

ABSTRACT

Optic disc pit (ODP) is a rare congenital anomaly of the optic disc that can be associated with maculopathy leading to progressive visual deterioration. The vast majority of cases are sporadic and no obvious factors have been correlated with the development of maculopathy. Optic disc pit maculopathy is defined by the concentration of intraretinal and subretinal fluid at the area of macula. Despite the advances in the imaging of the fundus, the origin of the fluid remains unknown and the exact pathogenesis of the maculopathy is not fully understood. Although some cases have been reported to resolve spontaneously, most cases require surgical intervention in order to treat ODP maculopathy and prevent loss of vision. Currently, there is no definite treatment for these patients and several surgical methods have been described, including pars plana vitrectomy (PPV) (combined with various techniques, such as inner retinal fenestration, autologous fibrin, and glial tissue removal), laser photocoagulation, intravitreal gas injection, and macular buckling. Overall, PPV remains the main form of surgical repair of ODP maculopathy. Although our understanding of the background and the pathophysiology of the disease has significantly improved, more studies are required in order to define the optimal treatment. This review summarizes the potential pathogenesis, as well as the diagnostic and therapeutic approach of ODP maculopathy.
