Spontaneous Regression of Optic Disc Pit Maculopathy in a Six-Year-Old Child.

ABSTRACT: A 6-year-old boy with a complaint of blurred vision for two months was referred to our clinic. His visual acuity was 20/32 in the right eye and 20/20 in the left eye. Optical coherence tomography (OCT) revealed optic disc pit maculopathy in the right eye. The patient was followed for 6 months without any treatment. At the end of the 6-month period, the patient's visual acuity was 20/20 in both eyes. The OCT imaging showed spontaneous regression of the optic disc pit maculopathy. In this case report, it is concluded that in children, spontaneous regression of the optic pit maculopathy with full recovery of visual acuity is possible. The development of optic pit maculopathy in childhood is rare and there are not enough studies on the treatment methods. Therefore, our case report may be helpful in the management of similar cases of pediatric optic disc maculopathy.

Project description:To demonstrate papillary imaging of eyes with optic disc pits (ODP) or optic disc pit associated maculopathy (ODP-M) with ultrahigh-speed swept-source optical coherence tomography (SS-OCT) at 1.68 million A-scans/s. To generate 3D-renderings of the papillary area with 3D volume-reconstructions of the ODP and highly resolved en face images from a single densely-sampled megahertz-OCT (MHz-OCT) dataset for investigation of ODP-characteristics.A 1.68 MHz-prototype SS-MHz-OCT system at 1050 nm based on a Fourier-domain mode-locked laser was employed to acquire high-definition, 3D datasets with a dense sampling of 1600?×?1600 A-scans over a 45° field of view. Six eyes with ODPs, and two further eyes with glaucomatous alteration or without ocular pathology are presented. 3D-rendering of the deep papillary structures, virtual 3D-reconstructions of the ODPs and depth resolved isotropic en face images were generated using semiautomatic segmentation.3D-rendering and en face imaging of the optic disc, ODPs and ODP associated pathologies showed a broad spectrum regarding ODP characteristics. Between individuals the shape of the ODP and the appending pathologies varied considerably. MHz-OCT en face imaging generates distinct top-view images of ODPs and ODP-M. MHz-OCT generates high resolution images of retinal pathologies associated with ODP-M and allows visualizing ODPs with depths of up to 2.7 mm.Different patterns of ODPs can be visualized in patients for the first time using 3D-reconstructions and co-registered high-definition en face images extracted from a single densely sampled 1050 nm megahertz-OCT (MHz-OCT) dataset. As the immediate vicinity to the SAS and the site of intrapapillary proliferation is located at the bottom of the ODP it is crucial to image the complete structure and the whole depth of ODPs. Especially in very deep pits, where non-swept-source OCT fails to reach the bottom, conventional swept-source devices and the MHz-OCT alike are feasible and beneficial methods to examine deep details of optic disc pathologies, while the MHz-OCT bears the advantage of an essentially swifter imaging process.

Project description:The emergence of extensively drug-resistant tuberculosis (XDR-TB) is a challenging paradigm shift faced by the TB control programs worldwide today. The treatment is further compounded with unique management difficulties faced in pediatric patients. Treatment of XDR-TB requires prolonged chemotherapy with second-line drugs which offer lesser potency and increased risk of drug-related side effects. We present a case of spinal XDR-TB in a child, managed with extended second-line antitubercular chemotherapy (ATT).A 6-year-old, Caucasian male child complained of persistent back pain for 3 weeks, with lumbar tenderness without neurodeficit. Radiographs showed fourth lumbar (L4) vertebral body collapse. Magnetic resonance imaging showed features suggestive of TB spondylodiscitis. The erythrocyte sedimentation rate (ESR) was raised. In view of the high prevalence rate of TB, on clinical suspicion, empirical first-line ATT (isoniazid + rifampicin + ethambutol + pyrazinamide) was given for 6 months, under the Revised National Tuberculosis Control Program (RNTCP). In the course of ATT, child developed iliopsoas abscess which was drained surgically. Repeat radiological evaluation showed almost complete L4 body destruction and 10 cm × 8 cm pre-vertebral abscess. ESR was further raised. Vertebral biopsy culture showed growth of Mycobacterium tuberculosis complex susceptible only to capreomycin (Cm). Second-line ATT (moxifloxacin + clofazimine + linezolid + isoniazid + amoxicillin-clavulanate + para-aminosalicylic [PAS] acid) with daily intramuscular Cm was initiated, under the RNTCP Programmatic Management of Drug-Resistant TB initiative. At 3 months, tenderness was absent, ESR decreased, and radiology showed consolidation of L3 and L5 vertebral bodies and their interspace. At 6 months, injectable Cm was stopped, oral ATT continued for 18 months. No major drug-related side effects were noted. At final follow-up, imaging showed complete L4 body absence, intact posterior elements, surrounding bony consolidation, resolution of abscess without neurodeficit, or deformity.XDR-TB should be suspected if there is clinical and/or radiological progression of TB in spite of chemotherapy or a prior history of treatment for TB. Effective treatment of XDR-TB requires a high index of suspicion and prompt, aggressive drug sensitivity-based ATT.
