外斜視兒童的近視研究

 Comparing myopic error in patients with basic and convergence insufficiency intermittent exotropia in China - PubMed (nih.gov)

比較外斜視兒童的慣用眼與非慣用眼的近視程度，非慣用眼的近視程度較高。

199位間歇性外斜視兒童，根據遠與近的斜視程度分為兩組，基本型(遠近斜視程度接近)與內聚不足型(近斜視明顯大於遠)。再進一步分類為屈光參差與非屈光參差。

結果

-內聚不足型之慣用眼等值球面度- 2.09 ± 1.45D，非慣用眼 - 2.53 ± 1.44D。

-基本型慣用眼等值球面度 - 2.46 ± 1.56D，非慣用眼 - 2.89 ± 1.37D 。

-兩組相同，慣用眼的近視程度顯著小於非慣用眼

其中屈光參差(雙眼屈光度差異大於等於1.00D)有43位，非屈光參差有156位。

-屈光參差組的近外斜量45.26 ± 24.41 PD，遠外斜量33.53 ± 23.31 PD

-非屈光參差組的近外斜量 43.42 ± 20.69 PD，遠外斜量 29.07 ± 16.84 PD

-兩組之間無顯著差異

散瞳劑與角膜塑型術(OK鏡片)的使用與兒童雙眼視覺相關研究

 Accommodation and vergence function in children using atropine combined with orthokeratology - PubMed (nih.gov)

62位8-12歲兒童分為四組，第一組結合使用0.01% atropine與OK鏡片，第二組使用安慰劑與OK鏡片，第三組使用0.01% atropine與鏡框眼鏡，第四組控制組使用安慰劑與鏡框眼鏡。

研究開始與三個月後，評估雙眼視覺功能，包括horizontal phoria, fusional vergence, the accommodative convergence/accommodation (AC/A) ratio, accommodative lag, and accommodative amplitude (AA)。

結果

1.調節遲緩僅OK鏡片組有顯著改進，其他三組未改變

Accommodative lag significantly decreased in the OK group (P = 0.002), but remained unchanged in the other three groups (all P > 0.05).

2.雙眼調節靈巧度與正相對調節在結合組與OK鏡片組有進步，其他兩組未改變

Binocular accommodative facilities and positive relative accommodations increased in the combination and OK groups (both P < 0.05) , but remained unchanged in the atropine and control groups (both P > 0.05). 

3.僅OK鏡片組的內斜位有顯著降低。

Only the participants with esophoria in the OK group had a significant decrease in esophoria (P = 0.008).

4.融像性聚散與AC/A在四組間無顯著差異

Changes in fusional vergence and AC/A did not significantly differ between the four groups (all P > 0.05).
