摘要

背景原发性玻璃体持续增生和原发性玻璃体静脉丛持续增生（PHPV/PHTVL）是原发性玻璃体正常发育的一种先天性异常。根据病情的严重程度，这种疾病可导致多种不同的并发症。单侧 PHPV/PHTVL 曾在一只视力受损但无白内障的幼兔身上出现过。本研究旨在描述一只对称、双侧、成熟白内障伴 PHPV/PHTVL 兔的临床特征、超声波检查结果、手术治疗和结果。双眼均出现完全性成熟白内障。尽管兔子完全失明，但其主人并未报告任何异常行为。眼部超声波检查显示玻璃体内有高回声线状结构，提示为 PHPV/PHTVL，双眼的检查结果相似。微血管多普勒（MicroV）能够检测到眼球后区域内的静脉曲张。结论和病例相关性本病例是首次报道由 PHPV/PHTVL 引起的兔子对称性双侧白内障。该报告强调了显微多普勒超声作为诊断技术的有效性。对兔子来说，白内障手术是可行的常规手术。

Bilateral cataract associated with persistent hyperplastic primary vitreous and persistent hyperplastic tunica vasculosa lentis (PHPV/PHTVL) in a dwarf rabbit

Background

Persistent hyperplastic primary vitreous and persistent hyperplastic tunica vasculosa lentis (PHPV/PHTVL) is a congenital anomaly of normal development of the primary vitreous. Depending on the severity, this condition can lead to multiple different complications. Unilateral PHPV/PHTVL has been described in a young rabbit with visual impairment but without cataract. The objective of this study is to describe the clinical characteristics, ultrasonographic findings, surgical treatment, and outcome of a symmetric, bilateral, mature cataract associated with PHPV/PHTVL in a rabbit.

Case description

An intact 2-year-old male dwarf rabbit presented with intermittent tearing. Complete and mature cataracts were observed in both eyes. Despite complete blindness, the owner did not report any abnormal behavior. Ocular ultrasound showed a hyperechoic linear structure in the vitreous, suggestive of PHPV/PHTVL, with similar findings in both eyes. Microvascular Doppler (MicroV) was able to detect blood flow in the tunica vasculosa lentis within the retrolenticular area. The surgery was conducted without significant complications, and functional vision was maintained postoperatively during the 4-month follow-up period.

Conclusions and case relevance

This case represents the first report of symmetrical, bilateral cataracts caused by PHPV/PHTVL in rabbits. This report highlights the effectiveness of microV Doppler ultrasound as a diagnostic technique. Cataract surgery could be considered a feasible and routine procedure for rabbits.

期刊介绍： The Journal of Exotic Pet Medicine provides clinicians with a convenient, comprehensive, "must have" resource to enhance and elevate their expertise with exotic pet medicine. Each issue contains wide ranging peer-reviewed articles that cover many of the current and novel topics important to clinicians caring for exotic pets. Diagnostic challenges, consensus articles and selected review articles are also included to help keep veterinarians up to date on issues affecting their practice. In addition, the Journal of Exotic Pet Medicine serves as the official publication of both the Association of Exotic Mammal Veterinarians (AEMV) and the European Association of Avian Veterinarians (EAAV). The Journal of Exotic Pet Medicine is the most complete resource for practitioners who treat exotic pets.
