まとめ
小児緑内障は,開角緑内障 (OAG) よりも視覚野の悪化が遅いことを示しており,進行のタイミングも同様です. ベースラインの視野状態は,両方のグループにおける長期的な結果の主要な予測要因である.
科学分野:
- オフタルモロジック (眼科)
- グラウコマ研究会 グラウコマ研究会
- 視覚野の分析 視覚野の分析
背景:
- 幼児の緑内障と成人における開角緑内障 (OAG) の長期的な視野進行に関する証拠は限られている.
- 進行率と予測要因を理解することは,小児および成人における緑内障の効果的な管理に不可欠です.
研究 の 目的:
- 幼児グラウコマとOAGの間の視覚野の進行速度とタイミングを比較する.
- これらの患者グループにおける最終的な視野状態の予測要因を特定する.
主な方法:
- 171の目 (87の小児緑内障,84のOAG) の遡及的観察研究で,視覚フィールドテストが≥3回,フォローアップが≥2年間行われました.
- 視野はOctopusの周回 (Gグリッド,TOP戦略) を用いて評価され,進行は平均欠陥 (MD) 率 (dB/年) によって評価される.
- 統計的分析には,マン・ウィトニーUテスト,カプラン・マイヤー,制限平均生存時間 (RMST),コックスモデル,多重線形回帰が含まれていた.
主要な成果:
- 小児グラウコマは,初期により悪いMDと,より高い手術率を示した.
- MDの進行率は,小児緑内障では -2.3dB/年,OAGでは 0.0dB/年であった (p < 0.001),これは小児症例では悪化が遅いことを示している.
- 無進行生存率と最初の進行までのタイミングは,グループ間で類似していました; ベースラインMDは最終的なMDの最も強力な予測指標でした.
結論:
- 視野の悪化は,より悪いベースライン状態にもかかわらず,OAGと比較して,小児グラウコマではより遅いようです.
- 現在の管理戦略は,小児緑内障の機能的安定に寄与する可能性があります.
- 個別的なフォローアップと適時な介入が推奨されています,特に小児グラウコマ患者の場合です.

Open Angle Glaucoma: Treatment
1.0K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
1.3K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Glaucoma: Overview
1.4K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Contact Angle
25.7K
When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Erikson's Theory on Socioemotional Development during Childhood
1.2K
Erik Erikson, a stage theorist, adapted Freud's theory to emphasize social factors in personality development throughout life, a concept known as psychosocial development. Unlike Freud, who focused on early childhood, Erikson believed that personality evolves across eight life stages, each marked by a specific challenge or "crisis." Successful resolution of each stage fosters competence, while failure may lead to feelings of inadequacy.

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
